Andexanet alfa, the active substance of Ondexxya, is a recombinant protein that acts as a decoy for the direct oral FXa
inhibitors apixaban and rivaroxaban in the blood.
Barron, A phase 2 randomized, double-blind, placebo-controlled trial demonstrating reversal of rivaroxaban-induced anticoagulation in healthy subjects by andexanet alfa (PRT064445), an antidote for FXa
inhibitors, Blood., 122, 3636 (2013).
The TF/FVIIa-mediated extrinsic coagulation pathway is inhibited by the tissue factor pathway inhibitor-1 (TFPI-1), a Kunitz-type inhibitor which prevents generation of FXa

(1) and (2), the forward resistance of the trawl FXA
and the traction force of the vessel (FTA) were calculated.
Thrombin generation is also downregulated by the tissue factor pathway inhibitor (TFPI), which inhibits TF-FVIIa and FXa
Distribution of florfenicol resistance genes fxA
and cfr among chloramphenicol-resistant Staphylococcus isolates.
Binding of the prothrombinase complex (FXa
, FVa, [Ca.sup.2+], and prothrombin) to the platelet membrane occurs in this step.
Moreover, as the levels of liver aminotransferases were also elevated, taking into account the hepatic effects of warfarin and since this patient emphatically refused intravenous drip injection treatments including heparin administration, we decided to switch from warfarin to the direct factor Xa (FXa
) inhibitor rivaroxaban (15 mg once daily) after confirmation that the PTINR value dropped to 1.85 on the seventh day.
In the study of TNF-[alpha] induced human umbilical vein endothelial cells (HUVECs), purpurogallin is demonstrated to inhibit both the activities and production of thrombin and FXa
. Hemostatic events are triggered in response to the vascular wall damage by exposure to blood existing in the endothelial extracellular matrix , which led to upregulate a series of coagulation cascades, including activated platelets, conversion of fibrinogen to fibrin, and amplified coagulation .
In turn, TF generates coagulant mediators (FVIIa, FXa
, FIIa, and Fibrin) that upregulate inflammatory mediators by means of protease-activated receptors (PARs) and TLR-4 [137-139].
